There’s plenty of nude beaches in America. I’m too much of a prude to be a nudist so I don’t have first hand info but the general impression I get from people I’ve known who have no issue with public nudity is that it’s generally presumed to be bad etiquette to be clothed at a nude beach.
That’s mostly an effort to keep the people away who only want to take pictures and video so they can get a few bucks from girls gone wild or some other BS.
Well here in NY there are a few on the Atlantic. Most notably being the one on Fire Island. No heterosexual man would be found dead there though. Not all of Fire Island mind you.
